Answer:
Surface area of the figure = 1,296π km²
Step-by-step explanation:
Given figure is a sphere;
Given:
Radius of sphere = 18 km
Find:
Surface area of the figure
Computation:
Surface area of the figure = Surface area of sphere
Surface area of sphere = 4πr²
Surface area of the figure = 4πr²
Surface area of the figure = 4π(18)²
Surface area of the figure = 4π(324)
Surface area of the figure = 1,296π km²
Median:15 1,11,14,15,31,37,47
Mean:22 (1+11+14+15+31+37+47)/7=22
Answer:
3 years
Step-by-step explanation:
let the number of years required be x
hence
42+x+44+x = 4(7+x+5+x+2+x)
86+2x = 4(14+3x)
86+2x = 56+12x
2x-12x = 56-86
-10x = -30
x = 3
Answer:
Step-by-step explanation:
- -4*(-2/5 + 3x) =
- -4*(-2/5) - 4*(3x) =
- 8/5 - 12x
Correct choice is D
